Data Structures for Coding Interviews in C++

Challenge: A Subarray with a Sum of 0

Explore how to determine if a list of integers contains a consecutive subarray with a sum of zero. This lesson covers the application of hashing strategies to solve this problem, helping you build skills for coding interviews and improve your problem-solving with C++.

We'll cover the following...

Statement

Given a list containing both positive and negative integers, determine if there exists a sublist of consecutive elements whose elements sum to zero. Return TRUE if such a sublist exists; otherwise, return FALSE.

Constraints:

  • 1≤1 \leq arr.length
